What do blood tests show?
Blood tests can also give your doctor an idea of how well your organs are functioning and if they've been affected by cancer. Examples of blood tests used to diagnose cancer include: Complete blood count (CBC). This common blood test measures the amount of various types of blood cells in a sample of your blood.
Depending on the test performed, most tests are completed and reported to your ordering healthcare provider within about 24 hours of receiving the sample for testing. Certain tests take several days to weeks. Results are sent directly to the ordering healthcare professional.
- Specifically, blood tests can help doctors: Evaluate how well organs—such as the kidneys, liver, thyroid, and heart—are working. Diagnose diseases and conditions such as cancer, HIV/AIDS, diabetes, anemia (uh-NEE-me-eh), and coronary heart disease.
- Daily, weekly, or monthly testing must indicate the time interval and frequency of testing. Expire after 12 months from initial request, or 24 months for patients requiring lifetime testing. Physician's office will be notified to submit a new lab requisition when a standing order has expired.
- Even though these findings may suggest leukemia, the disease usually is not diagnosed without looking at a sample of bone marrow cells. Blood chemistry and coagulation tests: Blood chemistry tests measure the amounts of certain chemicals in the blood, but they are not used to diagnose leukemia.
To test for chlamydia and gonorrhea, for instance, all that is required is a urine sample. For other STDs– like herpes, hepatitis, HIV and syphilis, a small blood sample is all the STD testing center requires. Many doctors' offices will test for STDs by doing an invasive (and sometimes painful) swab– we do not!
- You must wait 12 months after treatment for syphilis or gonorrhea before you are eligible to donate blood. You may donate blood if you have chlamydia, venereal warts (human papilloma virus), or genital herpes and you are feeling healthy and well and meet all other eligibility requirements.
- A small blood sample is drawn and then tested for antibodies to Chlamydia trachomatis. Chlamydia is not a blood-borne disease or infection, but the body creates antibodies to respond to various diseases and infections, and these can be found in the blood.
- Our doctors recommend testing for chlamydia 1-5 days post-exposure and gonorrhea 2-6 days after your sexual encounter. Re-test two weeks after treatment to confirm that you are clear of chlamydia and gonorrhea, then again 3 months later to make sure the infection did not re-appear.
Some rapid STD tests can give results within an hour. Other STD results make take up to 1-2 weeks to come in. This varies both by what test is used and what facilities your doctor's office has. Some doctors need to send out blood and urine samples to be tested.
- Common STD symptoms in women:
- No symptoms.
- Discharge (thick or thin, milky white, yellow, or green leakage from the vagina)
- Vaginal itching.
- Vaginal blisters or blisters in the genital area (the region covered by underwear)
- Vaginal rash or rash in the genital area.
- Burning urination.
- Painful urination.
- Pain during intercourse.
- You can eat or drink anything you'd like beforehand there's no need to fast. The other STD tests do not require any special preparation. If you are currently taking antibiotics, our doctors recommend waiting 1 week before getting tested for chlamydia, gonorrhea or syphilis.
- Generally, STD testing at a Planned Parenthood office in the US will carry a few different charges, including an exam fee and various lab fees. On average it'll cost you about $180* to test for the top four STD threats. However, this number can vary widely depending on where you are, your age and household income.
